Abstract

PURPOSE: To disable a cooling liquid discharge valve from opening so as to prevent unexpected empty heating by providing an inhibiting means for disabling opening operation of the discharge valve when a cooling liquid heating means such as a pulse burner can be ignited. CONSTITUTION: When a pulse burner falls in a ignition trying condition, an inhibiting means B for disabling opening manipulation of an oil discharging valve V is integrally incorporated with a slide type manipulating knob of a power source switch and an inhibiting plate 3 which extends and retracts in association with turning on and off manipulation of the knob 2. That is, when the knob 2 is turned rightward for turning on, the plate 3 extends to one side of a manipulation grip 1 of the valve V so that the grip 1 is inhibited from turning in an opening direction. Further, when the knob 2 is turned leftward for turning off, the plate 3 retracts to release the inhibition of turning of the grip 1. Accordingly, it is possible to eliminate a risk of empty heating due to lowering of the level of oil caused by discharging of oil.
